Dates on payments are not set by builder, so while playing in test set it.

Computer might not have access to it.

getId will nicely wait until methods will be executed, there is no need to use
serialize, which will commit new transaction.

If API has been called with loggable user, but without Person document (which

Delete is not in API, so implement request instead.
